Ruby

Attached a revised version of patch 5 with fiber_mark_self replaced by rb_fiber_mark_self. Thanks for the hint.

Applied in changeset r47959.

cont.c: Remove unused prev_fiber/next_fiber fields

They were added in r19890 (8a0d53a), with the explanation that it's a
double linked list of fibers in the same thread, but without any code
using them.

• cont.c (rb_fiber_t): remove prev_fiber/next_fiber
  (fiber_link_join, fiber_link_remove): remove functions
  (fiber_free, fiber_init, root_fiber_alloc):
  remove references to removed fields and functions

benchmark/bm_vm2_fiber_switch.rb: check for fiber performance

There are currently no benchmarks for Fiber performance, I
should've committed this years ago when [Feature #10341] was
implemented.
